Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978620, here are decompositions:

  • 29 + 4294978591 = 4294978620
  • 61 + 4294978559 = 4294978620
  • 67 + 4294978553 = 4294978620
  • 103 + 4294978517 = 4294978620
  • 109 + 4294978511 = 4294978620
  • 131 + 4294978489 = 4294978620
  • 239 + 4294978381 = 4294978620
  • 293 + 4294978327 = 4294978620

Showing the first eight; more decompositions exist.
